PILE.

Specification of Lettere Patent.

Patented June 29, 1909.

Application led February 26, 1909. Serial No. 80,119.

To all whom 'it may concern:

Be it known that I, FRANK ANTHoivr NoULLn'r, citizen of the United States, residing at N ew Orleans, in the parish of Orleans and State of Louisiana, have invented lnew and useful Improvements in Piles, of which the following is a specification.

My invention pertains to piles, and more particularly to piles such' as are employed for furnishing foundations for buildings in soils where the water line is below the average depth of building foundations.

My invention consists, first-in the provision of a method of expeditiously and easily forming piles in soil of the kind stated and in such manner that the piles are capable of sustaining great weight and all of the Aparts of each pile are thoroughly protected against the action of water and insects therein, and second-in a pile constructed in accordance with my method and constituting the product thereof.

With the foregoing in mind the invention will be fully understood from the following description and claims when the same are read in connection with the drawings, ac-

companying and forming part of this specil cation, in which:

Figure 1 is a vertical section illustrating acpile constructed in accordance with m invention as properly positioned in a body of soil. Fig. 2 is a similar view of the upper portion of the concrete and bag, and: Fi 3 -is a horizontal section taken through the ag comprised in my novel pile, in the plane indicated by the line 3 3 of Fig. 1.

Similar letters of reference designate corresponding parts in all' the views of the drawings.

It will be noticed by reference to Fig. 1 that I have indicated by lettering, the foundation line and the water line of the body of soil illustrated, and in practicing my iiivention I first drive a wood pile A down into the soil until the upper end or head of the said pile rests a material distance below the i water line in the soil. I have found from experiment that every purpose of my invention is served when`the upper end or head of the wood pile A is located approximately three feet below the water line. Subsequent to the driving of the wood pile A, a waterproof bag B, preferably a canvas bag treated in some suitable way to render it waterproof, is placed in the hole left above the wood pile A by the driving of the latter.

VThe said bag B is at its lower end thefull size of the head of the wood pile,` and is taperedor gradually reduced in cross-sectional size froiii the .surface of the soil to the head of the wood pile. In the said bag B three (more or less) feet of suitable concrete C is placed, andthe concrete is driven home or tamped by means 'of any suitable device, such for instance a follower (not shown) which is supeiposed on the concrete, and the hammer ofv a pile driver which is slowly lowered on the head of the follower, this in order to render the concrete compact and solid and to assure the bag B, of flexible material, snugly conforming to and resting tight" upn the head of the pile A and against. the wall of the hole leftby the drivin of the. pile. After the operation described the follower is removed and another section, say three feet, of concrete is placed within the bag, and the operation before described is repeated, and so on until the concrete comprised iii the improved pile is of the requisite length or height desired. I prefer to make the waterproof bag from finding its way into the bag throng the mouth thereof, and also to confin that part of the concrete piling C that extends above the foundation line. Subsequentl to the completion Vof the concrete portion of my novel pile, the portion of the Waterproof bag B above the bottom of the excavation is cut away from around the adjacent portion of the concretel pilin This is done so that the concrete foundation filled in around the piling will be directly againstand on tp of the concrete ile portion C without the interposition o any third substance between .the pile portion C and the concrete .foundation.

The bag B comprised in my im rovements serves the highly important o ce ofv pre-- venting any and all foreign substances from gaining access to and being commingled with t e concrete portion C, and this will be appreciated as an iiiiport-ant advantage when it is i'eiiieiiibered that it is the mixture of foreign substance with concrete precedent to setting of the latter that renders the concrete weak and brings about early deteriora- Attention is also directed to tion thereof.

The extension of the concrete portion C above the foundation or sub-grade line, as

- shown, is materially advantageous inasmuch as it assures the keying of the concrete foundation, and the strong binding of the same to the upper end of. the concrete pile` portion C.

in addition topthe practical advantages hereinbefore ascribed to my novel pile, it will-be manifest that the pile is made in a cheap manner of materials readily procurl able, and that the proper relative arrangeg ment and positioning of its elements may be expeditiously and easily eiieeted. Y y

As before stated, the construction herein illustrated and described constitutes the bestpractical embodiment of which l am cognizant, but it 1s obvious that in the'future practice of the invention such changes 'orlmedifications may be made as fairly fall within the scope of my invention as defined in the claims appended. y

Having described my invention, what l claim and. desire to secure by Letters-Patent,

1. The method of piling, which consists in first driving a Wood pile into soil until the head of the pile is disposed below the water line in the soil, then placing a Water-proof bag, of flexible material, in the hole and above and upon the wood pile, Vthen filling the bag with concretevto a point above a foundation or sub-grade line, and driving the concrete home to cause the bag and its contents to rest tight on and against the wood pile and also against the wall of thel hole left by thedriving thereof, and then removing the portion of the bag above the foundation or sub-grade line.

2. A pileV comprising a rigid ile-portion driven into soil until its hea is disposed below the water linein the soil, a water-proof bag, of flexible material, arranged in the hole, left by the driving of the rigid portion, and upon the head of the rigid portion, and concrete fully occupying the bag and eee,

my invention of extending above the upper end 'of the same and also above a foundation or sub-grade 1 line. g

3. The method of piling, which consists in first driving a Wood pile into soil until the head of the pile is disposed below the water. line in the soil, then placing in the hole left by the driving of the wood pile a Waterproof bag, otl flexible material, of sufficient size in cross-section to fully occupy the hole and of a length to reach from the head of the wood pile to a point above the Water line, and then placing and tamping suitable plastic material in the bagto distend and eause the bag to tightly fit against the upper end of the Wood pile and also against the wall of the hole.

l. A. pile comprising a rigid pile-portion driven into soil until its head is disposed below the water-line in the soil, and a waterL proof bag. of flexible material, containing suitable plastic material, placed in the hole left by the driving of the rigid portion and extending from the upper end of said rigid portion to a point above the water line.

driven into soil until its head is disposed beloiv the yvater line in the soil, vand a waterproof bag. of flexible material` filled with suitable plastic material and placed in the hole left by the driving of the rigid portion suitable plastic material and placed in the hole left by the driving of the rigid portion and extending from the upper end of said rigid portion to a point above the water line; the bag also extending up to a foundation or sub-grade line, and the plastic material, extending above said line.

'i'. T he method of piling which consists in first driving a rigid pile into soil, placing in the hole left by the driving of the rigid pile awaterproof bag, of flexible material, and placing concrete in the bag.

ln testimony whereof l` have hereuntoset my hand in presence of two subscribingwit# nesses.
